Diagnosis. Adult males of H. disjunctoides sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and tapered, inclined, apex projected towards the mesal region of gonopod ( Fig. 27A–D View FIGURE 27 ); presence of DP with the apex irregularly bifurcate ( Fig. 27A–C View FIGURE 27 ); solenomere long, taperad, apex truncated, projected towards the ventral region of the body ( Fig. 27A–C View FIGURE 27 ).

Description.

Size and form (holotype ♂). Body length = 44 and wide = 7 mm. TL/GW = 6.2.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson brown, antennomeres, sides of the metazonite, paranota, posterior region of epiproct and legs orange ( Fig. 26A–D View FIGURE 26 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 2.4 mm long, 6.5 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins slightly concave ( Fig. 26A, B View FIGURE 26 ). Rings 2–19: prozonite and metazonite smooth and shiny, without microgranulation in dorsal region of all rings. Anterolateral teeth on paranota of rings 2–4 ( Fig. 2G View FIGURE 2 ). Lateral margins of ring 2 projected posteriad ( Fig. 26A, B View FIGURE 26 ). Gonopodal aperture elliptical, approximately 1.5 mm wide and 0.5 mm long at midpoints. Telson ( Fig. 26D View FIGURE 26 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 27A, C View FIGURE 27 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 27D View FIGURE 27 ); distal region of the acropodite strongly sinuous, not bifurcate, curved ventrally at a 75° angle ( Fig. 27A–D View FIGURE 27 ); VP1 emarginated on posterior region, evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 27A, C View FIGURE 27 ); VP2 absent; LP1 long and tapered, inclined with apex projected towards the mesal region of gonopod ( Fig. 27A–D View FIGURE 27 ), LP2 and LP3 absent; presence of DP with the apex irregularly bifurcate and originating above the solenomere, projected to top ( Fig. 27A–C View FIGURE 27 ). Opening of solenomere located at distal end of acropodite, at lateral region, above LP1 ( Fig. 27A–C View FIGURE 27 ). Solenomere long, tapered, truncated apex, projected towards the ventral region of millipede body ( Fig. 27A–C View FIGURE 27 ).

Remarks. H. disjunctoides sp. nov. resembles H. disjuncta in the conformation of the gonopods and presence of DP ( Figs 10A–D View FIGURE 10 , 27A–D View FIGURE 27 ). It differs by DP being bifurcate in the apical region and extending beyond the distal region of acropodite. Besides, H. disjunctoides sp. nov. occurs on the south shore of the Amazon River ( Fig. 52 View FIGURE 52 ) while H. disjuncta occurs mainly on the north shore ( Fig. 50 View FIGURE 50 ), supporting the separation of the two species.

Distribution. Brazil: Pará ( Fig. 52 View FIGURE 52 ).

Etymology. The specific epithet is a combination of the name “ disjuncta ” and the Greek suffix “- oides ”, referring to the similarity of this species to H. disjuncta .
